Thanks but I'm an organic/fresh fanatic No way I would eat or drink powder/tabs/gel I don't know where they come from
But when I plan to ride hard and long, I found a very good site that teaches you how to make your own gel and purée.
It is quick to do, keep well in the fridge and cheap.

Unfortunately it is only in French  ... Google translate made significant progress recently, so I post it anyway.

I make this purée, the sweet one: http://www.diet-sport-coach.com/pages/content/produits-energetiques/compote-energie-maison-version-sucree-et-salee.html#L8uBQtspGfQH28Cy.99

And this gel: http://www.diet-sport-coach.com/pages/content/produits-energetiques/gel-energetique-booster.html#u7eu5MYuZfcrWG54.99

I pour them in silicone bottles like these: https://www.aliexpress.com/item/Free-Shipping-3pcs-Lot-Food-Grade-Silicone-Leak-Proof-Design-Travel-Tube-Squeeze-Refillable-Bottle-Empty/32373315663.html
That I put in my back pockets.
And they are easy to clean and reusable.

Alternating 1 purée / 1 gel each half hour.

Hi
How did the tyres set up tubeless and have you ridden wet tree roots or just dry hard pack.... How are they for sidewall protection. Im interested as 190g's a tyre lighter than my race king protections.

Thanks
Rick

One week ago I competed in this season's first race and finished 33/281 overall and 8/24 in my age group on 55 km/1390 meters of climbing in 2:19 hours. Not that bad for almost no training this year so far..
The bike performed great, I chose a 34 teeth chainring instead of the 36 teeth because of the alpine terrain. And I tested new tires from Michelin, the Wild Race'r Ultimate in 29 x 2.0 both @ 470 grams. The tire is similar to the Continental Race King, but provides much more grip even if it is so narrow.
The next race will be on the 17th of june. 60 km and 1650 meters of climbing, with lots of trails, so I will miss a full suspension bike there

Gret article carbonazza, I've been using SIS and high5 gels/electrolytes for years with no stomach problems and just like the buy a box and use them convenience.....

On my side, I've been using this as a replacement for Gatorade or any other drinks from the market this year with great results so far.

3 1/2 cup of water
1/4 cup of orange juice
1/4 cup of maple sirup
3 table spoon of lemon juice
1/4 tea spoon of salt

To be honest with you, the tire sucks.. The second race I rode them, I had one flat on the front tire and the rear tire was soft at the finish line. Protection = none. Nice experiment, but not good for racing. Also on wet roots, you might have too less grip. Tubeless setup was very easy, like I know it only from Schwalbe tires.
I switched back to the Rocket Rons 2.1 LiteSkin. Best compromise of good grip, easy setup, low rolling resistance and just enoug protection.

Thanks Jar.......

Can you share your programming?
I want to make my own carbon fiber holder

Well.. I think it's much about the ratio price/gram. Everything up to 1,50 € per saved gram is okay for me..
The Shift Up axle for the rear end is about 1,70 € per gram saved.

Other things like the Race Face Cranks come at 3,33 € per gram saved. That's pretty much, I think. But if you consider that you can sell the old part (SRAM X0 BB30 Cranks at 150 €), you may come to ~1,50 € per gram for the cranks. So this will be okay again  Almost the same for the cassette..

This is a new design for the seatpostclamp. Inspired by a friend of mine. Also I used more material, since you can easily grind of what is too much. The weight is with a steel screw. Titanium ones will come on the weekend. So finally it should be ~5 - 6g.
It tested this one with 4 Newtonmeters on the screw and it holds.

The next ones I build will get a titanium nut as well. This one is aluminum, just as the washer.

Do you mean how I built it? What do you want to know?

I used carbon fiber rovings, a tube with the same diameter as the seattube and epoxide resin. I soaked the fiber in the resin, and wrapped it around the tube and the bolt with the nut. After the resin was hardened, I grinded off excess resin. That's pretty much it.

A lot is trial and error. I did at least 4 seatclamps until I was satisfied with weight and function.

Order you some titanium bolts (https://www.jaeger-schrauben.de/Titan/Schrauben/Titan-TCK-natur::46.html)

and nuts (https://www.jaeger-schrauben.de/Titan/Muttern/Titan-MMSss-natur::1020.html) for example.

Can you share more pictures of your bike?
Flat or Gross?

Here we go 



And this is the bike:



Built for long distance marathon and CC races.

For the weight and to see if I can build (small) carbon parts by myself.

What do you mean by flat or gross? What I ride? Basically Cross-Country and Marathon.. If that answers your question: https://videos.mtb-news.de/49219/193302_20170616_140954?playhttp://

Sure, here are some Pics:

This is from summer before I changed the Race Face Cranks back to Sram XO1, because the non-driveside-crank arm was loose on the axle. It was not fixable anymore, so I changed it for a more reliable one.



Some pictures how the bike looks right now with about 7905 g: 











I will work a little bit on my roadbike this winter, too. So far I have only a couple of parts together. I'm still looking for a Sram Red Exogram Crankset and a handlebar. Most likely it will be a FSA K-Force handlebar. Maybe I will also strip the paint off the frame, but that's a whole lot of work. I found a fairly cheap frame, which has exactly the same geometry as the current frame, but weighs about 160 g less. Without paint it will sum up to maybe 200 g less. Lets see, what I can do about it 

That parts will save about 340 g in comparison to what I have currently:

[Jar_head]

As I said... It will be the FSA K-Force handlebar in 42 cm width. I already took off the paint from the first half.. with about 185 g the new handlebar will safe about 90 g in comparison to the aluminum handlebar that is mounted..
I have no scale at work unfortunatly.. but you can see in the last picture, that the painted half wheigs a lot more than the half without paint 

[Klaster_1]

I already took off the paint from the first half.

Jar_head, do you plan to strip the section that's gripped by stem faceplate? I was thinking about stripping my dropbar in order to achieve a stealthier look and this section stands out the most (it's white, duh).

[Jar_head]

No, I will leave the gripped middle section as it is. If you take it off, the diameter would be way less than 31,8 mm. The stem won't fit anymore.

What you can do anyways, is strip it and repaint that section with some transparent paint to the right diameter again.. could be a couple of layers of paint, but you will get rid of that white 

[Jar_head]

It's done for now.. 6,965 kg..

[Jar_head]

Long time no update 

Unfortunatly I didn't really have time to ride in the past months. But I had the chance to shoot a new road bike frame (70 % off  ) which is fairly light. Of course the color will come off the frame and the fork even though I meanwhile like it  I hope the set will be under 1000 g. That depens on how much paint will be on both, but it looks like a lot of paint.

Due to the PF30 BB I had to buy a new crankset too. Since I found no used SRAM Red compact cranks, I bought a new SRAM RED eTap 22 50/34 t crankset. That saved abaout 110 grams compared to the SRAM Red 22 GXP Cranks.
If there is the chance to change the rear hub body to an XD body, I can finally mount the SRAM Red cassette.. but that's another story.

The changes will give me a ~ 6000 grams roadbike......

Well, that's the new frame and how it will look like:
